My question is dealing with how many ancestors it took to produce me:
--> to produce me it took 2 people (my parents) = ($2^1$) people = 2

After my online research on the subject, I learnt that, biologically speaking, many scientists believe that there is no such thing as a race, because Homo sapiens species is only 200,000 years old, ...

People often say, including those with extensive knowledge in biology, that a certain species of animal will evolve in one way or another:
1.From changing environments.

I'd like to block a percentage of PGC-1β or Sod2 expression. According to the following paper's figure beta-blockers inhibit some expression of PGC-1α. Are there any medicines/chemicals which safely ...

I read in New Scientist recently that microchimerism occurs between previously born siblings and grandparents, not just the mother.
Do we know which parts of the genome are likely to be transferred? ...

Do genes that occupy a similar locus on the genome have correlated function, specifically in human beings? It is my understanding that adjacent genes are inherited together, and so location plays a ...

I can see from Wikipedia that there are possibly thousands of harmful mutations that have been cataloged and linked to disease. There are also unnumbered neutral mutations. But, does anyone know how ...

There are several companies (most notably 23andMe) providing SNP genotyping for individuals claiming that there is no sense for individual in obtaining full genome sequence since only small part of it ...

It is said that genes are partly responsible for the choices we make in our life; our genes help to create our environment, and then that environment can influence our personality. So, beside genes, ...
